人類垃圾導致赤狐入侵

挪威發展一些高海拔地區,建設了道路推廣旅遊業。發展除了增加野生動物被路殺的機會,人類遺留的垃圾也引來了赤狐及烏鴉來覓食。赤狐入侵嚴重威脅到北極狐的活動,並迫使牠們退移至較高海拔,加上赤狐體型比北極狐大,亦曾出現北極狐被赤狐殺害的情況。赤狐的遷移同時也對當區的生態系統及其他動物如岩雷鳥帶來威脅。

Norway developed road networks and tourism in the higher elevations. The increase of traffic caused more wildlife road kills, and human’s litters attracted red foxes and crows to come and search for food, causing threats to the arctic foxes there and forcing them to move higher up the mountains. Red foxes are also larger in size and there are incidences of them killing arctic foxes. The invasion of red foxes not only affecting the arctic foxes, but also other wildlife like ptarmigan and the local ecosystem.
